Provided are coating composition containing an organic polymer particle (A) composed of an organic polymer having a hydroxyl group and a cationic group in a molecule, the weight average particle size of which being 10 to 35 mum, and a base resin (B), wherein the content of the organic polymer particle (A) is 0.5 to 5.0% by weight in the solid content of the coating composition, and a method of producing the same, and a coating film and underwater structure using the coating composition. The base resin (B) has a group represented by the following general formula (1): -COO-M-OCO-A(1) (wherein, M represents a divalent or higher valent metal, and A represents an organic acid residue of monobasic acid) or a group represented by the following general formula (2): -COO-Si(R1R2R3)(2) (wherein, R1, R2 and R3, which may be the same or different, represent an isopropyl group or an n-butyl group) in a side chain, or has a cross-linking structure represented by the following general formula (3): -COO-M-OCO-(3) (wherein, M represents the same meaning as described above). |
